ORE-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 248,196, dated October11, 1881.

Application filed April To all whom it may concern:

Be it known that I, HANS J. MtiLLER, of the city, county, and State ofNew York, have invented a new and Improved Ore-Separator, of which thefollowing is a specification.

The object of my invention is to provide a new and improved device forseparating particles of iron, steel, 850., from granulated or pulverizedore or other material.

In the accompanying drawings, Figure 1 is a plan view of my improved oreseparator. Fig. 2 is a cross-sectional elevation of the same on the line00 ac, Fig. 1.

Similar letters of reference indicate correspondin g parts.

A solid or hollow cylinder, A, of steel or iron, is rigidly mounted on ashaft, B, journaled in the end uprights, C O, resting on a base-plate,I). A driving-pulley, F, is rigidly mounted on one end of the shaft, orthe shaft may be provided with other suitable devices for rotating it.Annular plates G G are fastened edgewise on the curved surface of thecylinder A at the ends, and like plates, H H are fastened to thecylinder a short distance Electro magnet wires I I are wound around thecylinder between these plates, whereby adouble pole is formed betweenthe coils. The wires from a dynamo-machine or a battery are held to theplate by the bindingscrews J and O, and the former of these screws restson the bottom of a spring strip of metal, K, the upper end of whichrests against an isolated ring, L, of the shaft. This ring L is attachedto a ring, M, rigidly mounted on the shaft B, and having a layer, N, ofinsulating material, on the side toward the ring L. The wire I passesfrom the end coil through the ring M, the layer N of insulatingmaterial, to the ring L. A hopper, S, is held parallel with thecylinderA by two standards, T, resting on the base-plate D. A platformor shelf, P, is supported below the hopper S by the rollers Q Q, andextends below the cylinder A to the central line of the same, quiteclose to the cylinder. Two jaws, c c, or a recessed plate, are attachedto the under side of the shelf or platform P, and the end d of an arm,0, of a shaft, k, passes in be- 11, 1881. (No model.)

tween the jaws c c, and the end of an arm, e, 50

of a shaft, k, provided with a tooth, r, is held against aratchet-wheel,f, by a spring, g. The base-plate D is provided with alongitudinal slot, Z, with beveled sides under the edge of the platformor shelf P. The base-plate D is provided with a like longitudinal slot,m, in the opposite side, these two slots being separated by alongitudinal beveled partition, n, extending upward within the outeredge of the rings H H and by which the sand and other non-metallicsubstances are arrested and compelled to fall into the slot orreceptacle l. A plate, R, rests on two side pieces, W, parallel with theend of the cylinder and extending in between the annular plates H H andresting on the base-plate D. The plate R is provided with transverseslots Y Y at the ends, through which slots screws X X pass into theupper edges of the side pieces, W, thus permitting the edge of the plateR to be adjusted at a greater or less distance from the cylinder A.

The operation is as follows: The pulverized material is placed into thehopper S and drops from there upon the platform or shelf P, which isvibrated by the action of the ratchet-wheel f on the tooth r of the arm6, and consequently on the arm '0 of the shaft 7s. The sand orgranulated material slides down the platform or shelf P, which isslightly inclined. The particles of iron or steel cling to the cylinderA, and are scraped from the same by the plate R, and drop intothe sloton or into the receptacle below it. The particles of sand or granulatedmaterials drop from the edge of the shelf or platform P into the slot 1or the receptacle below it.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The combination, with the hopper S and thecylinder A, of the inclined shelf P, extending with one end below thehopper, and the other below the cylinder, the rolls Q, the plate havingjaws c c, the shaft is, having arm e (I, .the spring g, arm 6, havingtooth r, and the ratchet-wheelfon shaft B, whereby the shelf isvibrated, as set forth.
